A new shingle roof is a major expense, so it’s tempting to put it off as long as possible. If you wait too long and the roof starts to leak, though, you can end up facing the stress and added expense of fixing interior water damage such as saturated insulation, peeling paint, crumbling drywall, moldy carpet, and ruined wood trim and floors. So how can you tell when it’s time for a new roof? You can take a proactive approach and use these warning signs as a guide for when to call an experienced roofing contractor to assess the condition of your shingles.
The expected lifespan of your asphalt roof can range between 15 and 30 years, depending on the type of shingle that’s installed. Generally, regular three-tab shingles last about 15-18 years, while architectural shingles have a lifespan of 24-30. Years of exposure to the harsh sun and the effects of heavy rain, high winds, hail, and other weather events can impact the longevity of your roof as well; so it may need replacement sooner.
Missing or Broken Shingles
As they age, asphalt shingles become brittle. They can break and/or tear off easier when it’s windy or raining heavily. It’s easy to replace a few missing shingles, but if there are numerous areas of damage on your roof, you’ll likely be warned that installing new shingles is the best way to prevent leaks the next time it rains.
Buckled or Curled Shingles
With long term exposure to the sun and weather, shingles may curl along the edges or raise and buckle along the middle. If you can identify areas on your roof where the material is buckled or curled, you can foresee potential trouble spots where rain can easily enter the attic if the raised shingles get lifted or torn off by the wind during a storm.
It’s normal for the outer layer of granules to gradually loosen, fall off, and get washed away as a shingle roof ages. If you see numerous dark “bald” patches from the ground, though, it’s a telltale sign that granule loss has reached a critical stage. Those patches are areas of bare shingle substrate that tend to break down faster when exposed to UV radiation.
